This SRAM product has steel ring gears and aluminum crank arms. I installed it on an old Specialized Rock Hopper. It replaced a Sugino all aluminum square taper crankset. I found that the Sugino Crankset wore out its aluminum gears and the bicycle's steel chain prematurely. Aluminum and steel grind on each other because the aluminum forms aluminum oxide, which is a very tough abrasive, and is actually a compound used in making cut -off wheels for cutting steel. My bicycle has an ISO, or European square bottom design, as opposed to a JIS, or Japanese design. There is a slight difference between the two designs. This SRAM crankset fit well on my bicycle, and with a new chain, the bicycle is functioning like new. The teeth on the ring gears grab the chain well, and there is no slippage.Read full review

It's not so easy to find the right replacement crankset for an older 8 speed MTB. I was looking for another Truvative like the one which came with my bike, and didn't know it was made by SRAM. Finally found this which actually says Truvative on the outer chainring. It is only slightly different than the original one, in that the two smaller chainrings each have 2 fewer teeth. Thats not a problem, as that's just going to lower the gear ratio for the steeper hills. I used a Shimano113mm square taper bottom bracket and it fits perfectly. Also fitted it with SRAM X4 shifters and derailleurs. I'm happy with it. Thanks SRAM !

This is a nice budget MTB crank. It is an upgrade over cheaper cranks that have riveted chainrings and stamped steel spiders. It has good pinning and ramps for fast smooth shifting and is very attractive with its matte black finish. It's a little heavy but the chainrings are steel for durability and longevity. Great for touring, commuting, city or budget mountain bike.

I bought 3 of this plain aluminium crank to use it as a tandem group, so I shorten it and reverse the pedal screwing. It's possible on this model because it's not in "U" form as Shimano's and it's plain inside so I can easily pierce new holes for pedals, sized for young children. Perfect !

I commute 12 miles round trip to work and needed to replace my old crank set. The SRAM S600 was very economical and works great! I highly recommend.
